UNITED STATES JAMES Y. BROWN, or KNOXVILLE, TENNESSEE" OVEN Application filed February 10, 1928. Serial No. 253,454.

This invention relates to stoves, and particularly to those 1n which ovens are installed.

It is an object of this invention to produce a stove having an oven which is removably at- 5 tached in place in order that it may be readily dislodged for the purpose of repair or the substitution of a new oven for one that has become useless.

Ovens are usually made of sheet metal, and

being subject to high degrees of heat, they are apt to warp and become distorted, and due to the presence of moisture, the metal may rust or otherwise deteriorate to an extent that replacement is desirable long before the other l5 parts of a stove become unfit for use.

It is a further object of this invention, therefore, to produce a replacement oven and install it through the employment of removable anchoring devices, such as bolts or screws, as distinguished from rivets, spot welding or the like, employed in the conventional types of cooking stoves and the like.

It is furthermore an object of this invention to produce a replacement oven with door frame and rear wall anchorage whereby the same may be secured .by fastenings to the door frame and back portion of the stove structure.

lt is a still further object of this invention to produce an oven replacement having a re inforced bottom, the vertical area being less than the original for the installation in a stove or range.

It is `furthermore an object of the invention to provide an oven for the purpose indicated, the ends thereof having oppositely bent flanges whereby the same can be expeditiously manufactured and installed and which will prove comparatively inexpensive.

W'ith the foregoing and other objects in view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

ln describing the invention in detail, reference will be had t0 the accompanying drawings forming part of this application wherein like characters denote corresponding parts in the several views, and in which- Pigure 1 illustrates a view in elevation of a front "of a'stove'in which" the invention is installed; A Figure 2 illustrates a sectional view on the 'line 2 2 of Fig. 1;

Figure r3 illustrates an view of thewoven", and p Figure tillustrates an enlarged detail 'view of the oven door, door frame ,and parts associated therewith. n

'In these drawings, 5 kdenotes a conventional type `of stove lor range having `the usual door 6, ka door support22,a back wall andflueSpf "underneath plan The oven embodying the invention yin the present"` showing is formed "angular in cross section yand consists of a fbottomk wa1l9,"a top wall 1Q, and two side waj'l'ls, such 'asl1.

The ybottom wall has an upwardly 'disposed tan'ge 13, .the top wall` a ydownwardly disposed flange 12,' and the side walls each has an inwardly disposed'flange 14 and they yare secured to the back wall Yof the range by. re-` movable fastenings y"15, lsudh as screws, v'bolts or the like.` It isfseen from .an inspectionof fFig.` '2 that the depth of the `flanges is `not very great. "Preferablythey arejust/sutli- 'cient to effectively' engage :the anchors by 'which the oven yis secur"ed"tothe back wall, as

vitis 'the purpose ofthe inventor that the inner y f vendfof the oven should ybezopen to as great'an areaas possible to permit ,Wheat radiating 4through the backwall to gain access to the oven. p y y The'b'ottom orthebottomwall') of the'oven 'is'reinforced ybya reticulated plate 16 and 'this plate lmay `be secured to the replacement oven by fastenings `'17,such as rivets, or it may besecured ,thereto by sp/otwelding or the like, butthe reinforcing plate serves to prevent buckling of the bottom and to strengthen the structure.

The front edge of the replacement oven at all of its sides is outwardly flanged, as shown at 18, and the flanges may have apertures, such as 19. The flanges fit against the front wall of the stove structure and fastenings 20, such as bolts, extend through apertures of the front wall, through apertures of the flanges of the oven, and through apertures 21 of a door frame 22 which bears against the cured in place.

langes 18, the door, of course, closing against the door frame.

It is desirable that the oven should be slightly less in height than the door opening, since clearance must be aorded for the reinforcing plateV as the oven is installed or removed.

It will be obvious from an inspection of the drawing that the replacement oven when applied to a range in the manner indicated will not present undue material and that the oppositely extending flanges serve to reinforce f the tubular replacement, while at the same time permitaccess tothe bolts whereby the oven is irmly anchored but removably secured in place to possess the vadvantages initially set forth.

It will be noted by reference yto the drawings that the oven which is placed on the market as an independent article of manufacture for replacement of originally burned outy ovens has at its front an outwardly extending flange which provides means for attaching the same to the front wall of the stove, and that the inner open end of the transversely rectangular structure has an inwardly projecting flange, both of the flanges being apertured for the reception of attaching bolts. It may also be noted that the reinforcing openwork grating which is attached to the lower side of the oven as supplied for replacement necessitates forming the oven of slightly less depth than the original oven which it replaces and for this reason the vertical height of the oven is slightly less than the opening through the front wall of the stove.

I claim:

As anarticle of manufacture, a replacement casing` for stoves andv ranges to provide an oven consisting of an open-ended rectangular casing having at its rear an inwardly extending flange with bolt receiving apertures therethrough and at its front an outwardly extending flange with apertures therethrough, the apertures formed through the flanges being in register with apertures through the frame of the stove or range and door casing, a reticulated plate attached to the bottom of the replacement member, the vertical area of the replacement being such that it may be passed through thefront openp ing of the stoveor range prior to being se- JAMES renown
